IMPRQVEMENT IN RAILROAD-CAR STOVES AND HEATERS.'

Specificaion forming part of Letters Patent No. 136,773, dated March 11,1873.

To all whom it may concern:

Be it known that I, JOHN Q. C. SEARLE, of Topeka, county of Shawnee,State of Kansas,

have invented-certain Improvements in Stoves and Heaters, of which. thefollowingis a specification:

' My invention has for its object the maintaining of a supply of waterat such a heat that it can be utilized by circulating it through pipesin a dwelling, railroad car, or cabin, in which the stove or heater issituated. I attain these results by surrounding the fire-pot A with awater-reservoir, B, containing flues for the passage of the products ofcombustion, and by the employment of a pump, F, by which the heatedwater may be caused to circulate through heating'pipes communicatingwith the reservoir. As the reservoir B forms the walls of the firepot,the water must necessarily be heated rapidly, while it protects thepotfrom the injurious effects of the heat. I cause the products ofcombustion to descend through the lines D D into a smokechamber'at thebase of the stove or heater, and to ascend through flues E, all theselines passing through the reservoir, so that the water may deriveadditional heat from the products of combustion. When it is desirable toutilize the heated water by causing it to impart heat to the room, car,or cabin, in which it is situated, I combine with the reservoir a rotaryor other suitable pump, F, and a circulating pipe or pipes, G, so that adetermined flow of water may be maintained through the reservoir andpipes, the latter being continued to such points as may be desired.

This plan may be adopted with special advantage in railroad cars, as thepump can be readily driven from one of the axles, and it insures adetermined circulation, which cannot be interrupted by frost as in otherwaterheating apparatus used on railroad cars.

1 claim as my invention- 1. The combination, with a water reservoirsurrounding a tire-pot, of fiues D E extending through the saidreservoir, and so arranged that the products of combustion shall passdown through one flue or set of flues and up through the other,substantially as described.

2. The combination, with a water-heating reservoir, and with a pipe orpipes communicating therewith, of a pump, or its equivalent, forcreating and maintaining a determined circulation through the saidreservoir am pipes.

3. The combination, of the said pump, or its equivalent, with arailroad-car stove and a water-reservoir, and with devices for operatingthe pump.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN Q. G. SEARLE.
